Overview
SIRIUS applications
We support you where UL is concerned
Product liability laws in the USA are way stricter than in Europe.
Whoever plans to export products to North America should have
them UL-certified, particularly when it comes to electrical equip-
ment. We can help you with our comprehensive know-how and
broad portfolio of UL-certified low-voltage controls.
Who or what is UL?
UL (Underwriters Laboratories Inc.®) is one of the world’s
leading organizations for testing and certification in the field of
product safety. This independent, nonprofit US organization was
founded in 1894 at the request of American fire insurance
companies to analyze the fire hazards posed by electrically
operated devices.
Today, UL tests and certifies the most varying materials, compo-
nents and end products for their reliable operation, particularly
with regard to potential personal injury and fire formation. The
organization maintains subsidiaries in numerous European
countries. For detailed information on the US organization as
well as contact details for the various European subsidiaries
see www.ul.com

Differences between UL and IEC
The IEC standards for the IEC market merely specify the
minimum safety requirements of a device or system. Technical
details of the safety requirements’ constructional implementation
are up to the manufacturers.
In contrast, the standards for the American market are far more
detailed. Depending on the standard, the required process may
be monitored from product design to product production down
to application, mounting and operation.
NFPA79 is the electrical standard for industrial machinery
outside the control cabinet. As such it differs from and is the
counterpart to the control cabinet standard UL 508A.
UL partner since 1969
Enlisting the expertise of a partner such as Siemens is a wise
move for anyone who wishes to avoid unnecessary aggravation
and save both time and money.
Ever since 1969 our production facility in Amberg, where the
complete diversity of our low-voltage controls and distribution
portfolio is developed and produced, has been working closely
with Underwriters Laboratories Inc.
Our consideration not only of EU directives and IEC standards
but also UL standards begins as early as in our products' devel-
opment phase. This has resulted in a wide-ranging portfolio of
UL-certified low-voltage switchgear, controlgear and protection
circuit technology.
As a result we have comprehensive know-how on the subject of
UL certification and approval, ranging from production down to
the wiring of control cabinets (panels) according to UL stan-
dards, and we would be pleased to pass this knowledge on to
you as part of our application consulting service.
Our portfolio of low-voltage controls ensures your being on the
safer side in terms of UL and facilitates the easy and fast
assembly of control cabinets according to UL.
